To all whom z' may concern:

Be it known that I ANDERS JORDAHL, a subject of the King of llorway, and resident of New York, in the county and State of New York, have invented certain new. and useful Improvements in Dust separators, of which the following is a specication.

. This invention relates to dust separators designed to protect the sensitive parts of machinery, apparatus, and instruments, from the destructive action of dust, grit, and other foreign matter contained in the air, and is especially applicable to turbogenerators, motors, air compressors, gasoline engines, tractors, motor trucks, gas locomotives, and other apparatus and devices.

The invention has 'for one of its objects, to provide a device of the character specilied, simple in construction, positive and e'ffective in operation, durable in use, adapted to be readily installed and occupy a minilnum amount of space, and capable of thoroughly cleansing a-maximum amount o air 'and gasin a minimum amount of time.

l'lo that end, a device is herein provided having an extended surface area for a large volumclof gas'or air to pass over, and having sullicient air passages to permit the gas or air to pass rapidly through said separator in the shortest path of travel compat- Aible with a maximum possibility of forcing air in contact with the surface ott the separating element. p

With the foregoing and other objects in view, hereinafter stated, the invention consisting of the device hereinafter described, and illustrated in the accompanying drawings, which shows the preferred embodiment of the invention, but changes, alterations and modifications thereof may be made therein, without departing 'from the invention. As illustrated in the accompanying draw- 1n s deignate corresponding partsl throughout the several views,

Figure 1 is a side elevation of a separating1 member embodying my invention.

igure 2 is a horizontal sectlon taken on the line 2 2 of Figure 1, and

Figure 3 is a horizontal section of a separating member embodying a modification of the invention. Y

The separating member illustrated in the drawings comprises a plurality of rows of elongated elements, preferably arranged in in which similar reference numerals having the capa ility of serving as retain- -ing means to hold the separator elements together, and at the same time permit -air and gas to be forced against the side of the separating members in a direction perpendicular to the plane of the side walls of said member. The hollow, elongated elements comprising the separating member, and the screens or 'walls holding them together, may be coated with a viscous fluid adapted to retain a considerable portion of dust, dirt, and other foreign matter filtered from the air .or gas thatpasses through the separating member.

As illustrated in Fig. l, the filtering elements are made of a sheet of metal 3 and .provided with small apertures 4 formed in the .wall of said elements. The apertures o f the wall of said element are made of a size suiicient to enable the air or gas to be readily forced through said apertures, and the wall may be coated with -a viscous lu'id, and the elements arranged in line with each other as shown in Figure 3, or in staggered relation to each other, as shown in Figure 2.

It is not essential that the apertured tubular members be made in 'cylindrical form, and if desired they ma be made rectangular in cross section as s own in Figure 3.

When the device is in use, and enclosed within a suitable casing, having an inlet aperture and an outlet aperture with the axis of'. the inlet aperture substantially perpendicular to the side wall of the separating members, air or gas entering the 'casing will be forced against the side walls of the separating members and de4 osit dust and dirt on the viscous coating o said walls, to such an extent that when the gas or airis Adischarged from the se arating member, it will e substantially ree from .all foreign matter. y

Some of such foreign matter will drop down into the bottom o the casing and a hopper having a discharge gate may be connected with said casing to clean out the interior of the casing.

-The elements comprising the separating member may be removed from the casing, cleansed, and re-coated with viscous flui and replaced in their working position.

Because of the extended length of the elements of the separating member and the body formed by a plurality of said elements, a large surface area is presented to the air or gas entering the casing, and because of the elements being hollow, an inner and outer wall is presented by each element to the gas and air` passing through and between said elements, thereby enabling a maximum quantity of gas or air to pass through said member or between the elements thereof in a minimum amount of time.

The shape and formation of said elements is such that air and gas passing through the apertures formed therein is directed from a straight line and deflected in all directions laterally and vertically, so that every portion of said elements, inside and outside, operate whencoated with a viscous fluid to remove all foreign matter from air or gas passing through the separating member.

What I claim as new and desire to secure by Letters Patent is 1. A filtering member comprising a plurality of rows of tubes extending in a common direction in contacting relation with each other, each row forming two walls with spaced outwardly extending portions of the tubes extending across the faces of the t'wo walls of the tubes, and each tube having a series of spaced apertures on each vside of each of said extending port-ionsnf the `ytube providing fluid passages through the walls of the filtering member formed by the tubes whereby the fluid inpassing through the filtering member will be deflected from the direct passage normal to the filtering member and fluid currents entering the apertures of the tubes on opposite sides of the extending portions of the tubes will impinge upon each other within the tubes and be -deflected and pass through apertures on opposite sides of the extending portions through the other sides of the'tubes.

2. In a filtering member, a row of Vtubes extending in a common direction with their sides in contacting relation with each other so as to form a wall, and each tube having a series of apertures in each side portion between the contacting portions and the outermost portions of the tube and the apertures in each series in common planes normal to the axes of the tubes and directed toward the center of the tubes through the walls thereof. l

3. In a filtering member, a row of tubes extending in a common direction with their sides in contacting relation with each other so as to form a wall, and each tube having a series of apertures in each side portion between the contacting portions and the outermost portions of the tu e and alongthe contacting portions thereof and the apertures in each series in common planes normal to the axes of the tubes and directed toward the center of the tubes through the walls thereof.

4. In a filtering member, a row of tubes extending in a common direction ywith their sides in contacting relation with each other so as to form a wall, and each tube having a series of apertures in each side portion between -the contacting portions and the outermost portions of the tube and along the contacting portions thereof and the apertures in each series in common planes normal to the axes of the. tubes and directed toward the center of the tubes through the walls thereof, and a second row of tubes similarly arranged and provided with apertures in the same spaced relation and having the side portions of the tubes on one side of said second row in contacting relation with side portions of the tubes of the first row of tubes and the apertures in such contacting sides of each row forming passages from one row of tubes into the other row of tubes.

In testimony that I claim the foregoing as my invention, I have signed my name f hereunder.

ANDERS JORDAHL.
